What lens is typically used on patients with recurrent epithelial erosion?

The lens that is typically used on patients with recurrent epithelial erosion is the bandage lens. This type of lens is designed to protect the corneal surface and facilitate healing by providing a smooth refractive surface over the cornea, while also reducing pain and discomfort. Bandage lenses are especially beneficial in cases of epithelial erosions as they can help to stabilize the cornea, prevent further damage, and promote epithelial regeneration.

These lenses are usually made from soft silicone hydrogel materials, which allow for oxygen permeability and are comfortable for extended wear. By acting as a protective barrier, the bandage lens allows the epithelium to heal, reducing symptoms associated with exposure to the environment, such as irritation or light sensitivity.

In contrast, other lens types mentioned may serve different purposes. For instance, a piggyback lens may involve using two lenses together but is less commonly indicated for epithelial erosion specifically. Scleral lenses provide vaulting over the cornea but are typically used for more severe conditions affecting the cornea or irregular astigmatism, rather than for simple epithelial erosion. Truncated lenses are generally designed for specific visual requirements, such as in the realm of orthokeratology, and do not have the protective function needed in cases of epithelial
